Description
The A8513 is a single-output white LED (WLED) driver for LCD backlighting. It integrates a current-mode boost converter with an internal power switch and one current sink. The A8513 can operate from a single power supply from 4.5 to 40 V, to accommodate start/stop, cold crank, and load dump requirements. A 2 MHz boost converter switching frequency allows the A8513 to operate above the AM radio band.
